Google Print puts the content of books where you can find it most easily; right in Google search results.
To use Google Print, just do searches on Google as you normally would. Whenever a book contains content that matches your search terms, we'll show links to that book in your search results. Click on the book title and you'll go to a "content page," where you can see the page containing your search terms and other information about the book. You can also search for other topics within the book. Click on the "Buy this Book" link and you'll go straight to a bookstore selling the book online.
The service is in Beta stage.
